全自动大孔树脂吸附机组

AUTOMATIC MACROPOROUS RESIN ABSORBING UNIT

大孔树脂吸附分离机组特点：

大孔树脂吸附分离技术是采用特殊的吸附剂，从中药复方煎液中选择性地吸附其中的有效部分，去除无效成分的一种分离纯化新工艺。可以解决中药生产中所面临的剂量大、产品吸潮和重金属残留等实际问题。经大孔树脂吸附技术处理后所得到的精制物，可使药效成分高度富集，杂质少，提取得率仅为原生药的2～5%，而一般水煮法为30%左右，醇沉法为15%左右；可有效地去除吸潮成分，有利于多种中药剂型的生产，并增强产品的稳定性；可有效地去除重金属。大孔树脂吸附分离工艺所得提取物体积小，不吸潮，容易制成外型美观的各种剂型，尤其适用于颗粒剂、胶囊剂、片剂等的生产，使中药的粗、大、黑制剂升级换代为现代制剂。该技术将是对中药提取工艺影响、带动面的技术进步之一。

Characteristics of macroporous resin absorbing and separating unit：

The macroporous resin absorbing and separating technology is a new separation and purification technology that adopts special absorbent to selectively absorb the effective parts from the boiled compound liquid of traditional Chinese medicine and remove the ineffective components. It can solve the problems of high dosage, product moisture absorption and heavy metal residual etc. during the production of traditional Chinese medicine. The refining products obtained through the macroporous resin absorbing technology will make the effective components of medicine higher with low impurity, and the extracting rate is only 2~5% of crude drug, which is about 30% through water boiling method and 15% through alcohol precipitation method. It can effectively remove the moisture absorbing components to facilitate the production of various traditional Chinese medicine injections and enhance the stability of products. It can effectively remove the heavy metal. The extracts obtained through the macroporous resin absorbing and separating technology have small volume without moisture absorption, which can easily be made into various injections with beautiful appearance and are especially suitable for the production of particles, capsules and tablets etc., so as to upgrade the rough, big and black traditional Chinese medicine preparations into modern preparations. The technology is one of the technical advances that influence most and drive extensively the extracting technology of traditional Chinese medicine.
